Babies made without mothers could come sooner than we think, leading biologists claim.
Late last year, a team at the University of Bath discovered that sperm and skin cells - or any other kind of non-egg cell - might be all you need for conception.
At the time, they said the scenario of men conceiving with men was ‘speculative and fanciful’.
But in a new report published today, the top embryologists at Harvard and Brown Universities urge nations to begin contemplating the legal minefield that would surround mother-less babies.
‘With science and medicine hurtling forward at breakneck speed, the rapid transformation of reproductive and regenerative medicine may surprise us,’ they write.
